廃棄処分されるのが一般的である。2. Description of the Related Art In recent years, expanded polystyrene products have been widely used in the fields of packaging and transportation, but used expanded polystyrene products are discarded as waste from households and factories, and incinerated. It is generally transported to a landfill or landfill and disposed of.

ても強く望まれていた。However, since the waste of the expanded polystyrene product has a large capacity, it is bulky when it is stored as dust, which is an obstacle, difficult to handle and difficult to carry, and also burns when it is incinerated as dust. Since the temperature is high, there is a problem that a large amount of combustion energy is required and damage to the incinerator is accelerated. Furthermore, the disposal of used expanded polystyrene products as waste without reusing them also results in the waste of global resources, so the development of new recycling methods requires packaging and transportation. It was strongly desired not only from the technical field but also from the general public.

ていない現状である。Therefore, recently, pelletized synthetic resin recycling raw materials have been processed from the recovered expanded polystyrene products, but the expanded polystyrene products are bulky and are therefore used for recovery and transportation / storage at a recycling plant. It requires a lot of trouble and a large space. In order to reduce such troubles and places, it is possible to melt or press-compress the collected expanded polystyrene product at the collection site, but when the material is heated to the melting temperature, the properties of the synthetic resin itself will increase. However, there is a problem that it cannot be reprocessed into a high-quality synthetic resin raw material, and a large-scale press machine is required for pressurization and compression.

低減した点に特長がある。In the present invention, a used bulk polystyrene foam product is directly recovered and brought into a synthetic resin recycled raw material factory for processing, or the recovered polystyrene polystyrene product is melted as it is or under pressure compression treatment. , The temperature of the synthetic resin itself does not change and is crushed to a required size that is easy to press at the collection site, rather than bringing this melt into the synthetic resin recycled raw material factory for processing. It is heated to a small size and compressed into a plate shape with a small press pressure, and brought to a processing plant for recycled synthetic resin raw material without being bulky, or the compressed plate shape at the collection site is subsequently cut into strips. Pack this in a bag and bring it to a processing plant for recycled synthetic resin raw materials in a bulky state to reduce the number of labor and places for transportation and storage, and to increase the size. A synthetic resin reclaimed materials without the use of Do processor, there is a feature in that greatly reduces the series of recovery cost.

とすることできないことを確認した。[0008] Further, by the heating compression, air, gas, and water contained in the expanded polystyrene product are evenly released, and an extremely thin plate-like material can be obtained. That is, according to the experiments of the present inventor, the air, gas, and water contained in the expanded polystyrene product can be released to some extent by mere compression, but most of them are compressed and deformed while existing inside, and the press pressure is released. After that, it was confirmed that the internal gas and the like could not be expanded or restored to a non-foamed state or a state close to that.

再生原料素材とすることができる。The above-mentioned warm compression is applied to a used expanded polystyrene product crushed into, for example, a fist size.
It is carried out by pressing for 1 to 2 minutes with a pressing pressure of about 0 kg / cm 2 , and at this time, the pressing body is 50 to 100.
It is preferable to heat and keep it at ℃. The reason is that when the temperature of the pressed body is less than 50 ° C, it takes time to uniformly release the air, gas, and water contained in the expanded polystyrene product, while the temperature of the pressed body is higher than 100 ° C. In this case, there is a problem in compression processing when the polystyrene foam product is cured by heat, and the properties of the synthetic resin recycled raw material that has been made into a plate shape change, and a good quality synthetic resin recycled raw material after being recycled into pellets is obtained. Because I can't. The invention of the present application initially produces an expanded polystyrene product of 15 to 20 g / liter by performing such warm compression.
Compressed to about 30/1/15 to 200-300g /
It is possible to use 1 liter of synthetic resin recycled raw material in a non-foamed state or a state close to that.

Filled up. Next, a press body heated and kept at 70 ° C. was lowered from the upper part and pressed at a pressure of 20 kg / cm 2 for 1 minute to produce a thin plate-like synthetic resin recycled raw material having a thickness of about 2 mm. The obtained thin plate-shaped synthetic resin recycled raw material has a unit weight of 300 g / liter, which is more compactly compressed than the original expanded polystyrene product, and air, gas, and moisture are evenly released, and there is almost no foaming. It was in a state or a state close to it, and could be transported without being bulky. This was directly brought to a processing plant for synthetic resin recycled raw material, cut into 10 × 10 mm squares, and reprocessed into a synthetic resin recycled raw material by a conventional method. As a result, a very good pelletized synthetic resin raw material was obtained. ..
